Major new features:
+* A per-thread cache has been added to malloc. Access to the cache requires
+ no locks and therefore significantly accelerates the fast path to allocate
+ and free small amounts of memory. Refilling an empty cache requires locking
+ the underlying arena. Performance measurements show significant gains in a
+ wide variety of user workloads. Workloads were captured using a special
+ instrumented malloc and analyzed with a malloc simulator. Contributed by
+ DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
+
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
